IMPROVEMENT IN HORSE-RAKES.

Specification forming part of Letters PatentNo. 25,535, dated September 20, 1859.

To all-whom 'it may concern.-

Be it known that I, THEODORE J. STEFFE, of the city of Lancaster, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Improvement. on Horse-Rakes, by which the several devices used all operate on the axle of the machine as their common center; and I do hereby declare that the following is afull, clear,aud exact description of the construction and operation of the same, reference being had to the annexed drawiugs, making a part of this specification, in' which-- Figure l is a perspective view of the several parts in place on the axle; Fig. 2 the round iron axle over or around which those devices are put. Fig. 3 shows the lifters b and lever G connected by the rod B, Fig. 4 shows the cleaners c couuected'in like manner by the rod 0 and attachment of its brace K L. Fig. 5

illustrates the operation of the lever G (cen-.

trallyplaced) on the brace K L, lifters b, and cleaners c. Fig; 6 shows one of the oval-eyed tooth-heads E, with a tooth, D, inserted and held by the key N, which has a hole, through which one end otla spiral spring is passed (F) from the rod B under each tooth. Fig. 7 shows the cleaner-brace K L, hinged at I I, with its slot 0 and slide M.

The projecting and E of the lever G is ar-- rested by the slide M when brought over the sloto, and thereby draws the cleaners 0 downward as the teeth rise upward, and effectually removes all that might lodge upon them. When 0, and the teeth are kept up by a pin through thread. By this arrangement any injured piece can be readily replaced at a great saving of time and expense, as the entire rake can be taken apart and put together again in twenty minutes, besides adapting this rake admirably for transportation, storage, 850., as its separate pieces occupy but a small space when packed away, and in every other respect fully .equal to any other devicefor operating in the field.

I am aware that, separately considered, it may seem to offer nothing newor novel; but, taken collectively, it'is the opinion of all who have examined it to be both novel and useful. I do not claim any of its parts, therefore, separately considered.

What 1 ciaim as my'invention, and desireto secure by Letters Patent, is-

1. The arrangement and combination of the teeth-aheads E, key N, spiral-sprin g attach menl F, lifters b B, lever G H, cleaners c 0, when these several parts have their centerof-motiou outhe axle ofthe machine.

2. In combination with the above, the footbrace K L, hinged at ,l I, slideM, and slot 0, substantially as and for the purpose herein specified.

THEODORE J; STEFFE.
